9- Claims.

The present invention relates to a means for winding and cuttingmaterial which is packaged in roll form to obtain sheets of thematerial; the means being particularly applicable for use in connectionwith fCellophane webs.

Heretofore various devices have-been employed for cutting Cellophane butthey have generally been of a complicated mechanism and thereforeprohibitive to the consumer of small quantities 10 of the material.

An object of the invention therefore is to provide a simplified devicefor cutting sheets of Cellophane from rolls of the material which iswithin the means of the small consumer 15 thereof. I

Another object of the invention is to provide a novel means of cuttingthe Cellophane which is positioned upon the winding reel proper.

A further object of the invention is to provide no a device which isquickly assembled for operation and which occupies a small space whennot in use.

Other objects will become apparent from the following specification anddrawing, in which: 25 Fig. 1 is a front elevational view of the deviceof my invention.

Fig.2 is an enlarged view taken on line 2--2 of Fig. 1, only partthereof being shown in cross section. 80 Fig. 3 is a cross sectionalview taken on line 3-3 of Fig. 2.

Fig. 4 is a perspective view of the cutter means of my invention similarto the form shown in Fig. 2.

85 Fig. 5 is a cross sectional view taken on line 5-5 of Fig. 2.

Fig. 6 is a cross sectional view of a modified form of cutter means.

The preferred embodiment of my invention 40 consists of a roll ofCellophane 8 or similar material, wound on a core 9 which is rotatablymounted on a horizontally extended axis ID. The axis is positioned onany convenient supporting base I I, such as a vertical wall by means 45of a plate l2 integral with the axis and fastened to the wall by bolts[3.

A web IQ of Cellophane which is to be cut into sheets is taken from theroll by a winding reel (generally indicated as l5) which comprises 59 arotatable frame l6 having two adjustable arms l1 .and I8 intermediatethe ends thereof. The frame is mounted on a centrally disposed axis l9which is in the form of a threaded lug extending outwardly from abracket 2|! and which is fastened to the wall It by means ofscrews 2|.

The frame is also provided with longitudinal slots 22 and 23 whichextend radially from the axis thereof to position the arms in adjustablespaced relationship thereon. The arms l1 and I8 are mounted in the slotsof the frame by means of 5 integral shoulders 24 and 24' and threadedportions 25 and 25' respectively, the latter being adapted to receivewing bolts 26. To preclude rotation of the arms whilst the reel is inoperation or when the bolts are tightened to the frame the arms arefurnished with square portions 21 and 21' respectively (Fig. 5) whichextend from the abutting surface of the shoulders. and 24 and partiallyinto the slots 22 and 23.

The Cellophane cutting means for the device l is incorporated in the armI! which is preferably made of hollow tubing. A rod 28 is held in thearm (Fig. 3) and is of smaller dimensions than the hollow portion of thearm to allow horizontal movement of the rod therein. The rod is furgonished with a vertical slot 29 at its inner end which encloses the lowerend of a knife 30, a countersunk screw 3| being provided to fasten theknife to the rod. A longitudinal slot 32 formed. in the uppermostportion of the arm 11 provides an opening or way from which the knifeprojects and. also functions as a guide in which the knife may move todetermine its limits of .motion. In order to obtain an efficient cuttingaction, the plane of the knife edge 33 is positioned at an obtuse anglerelative to the plane of the work. To provide a simple means ofassembling the rod and the knife in the arm I! a circular bore 34 ismade in the tube which is adjacent the position of the parts and in linewith the 35 counter-sunk screw 30.

An extension 35 of the rod beyond the free end of the arm I! furnishes ahandle whereby the reel may be rotated to wind the Cellophane" thereonand also provides a means of pulling the knife outwardly, through theCellophane to sever it into desired sheets. As indicated in Fig. 3 theshoulder portions 24 of the arms 11 and I8 are provided with a smallindicator point 36 which in conjunction with the calibrations 31 madealong the edge of the frame l6 determines the exact positions at whichthe arms are to be adjusted to'obtain any desired length of sheet fromthe Cellophane" web.

A modified form of cutting means is shown in Fig. 6. There the arm I!has a longitudinal slot 32 for guiding the knife 38. The rod 39 enclosedin the tubing has much smaller dimensions than the hollowed portion ofthe arm to allow vertical movement of the rod in the tube. The knife Ito cut through the obstacle encountered. It is contemplated that thisarrangement may be used in conjunction .with the form of knifeillustrated in Figs. 2, 3, and 4..

In operation the material from the roll 3 is secured in any suitablemanner to the arm H of It is to be understood that my device is notlimited to its use for Cellophane and may be used with other forms ofWeb material from which sheets are to be cut.

What I claim is:

1. In a device for material, the combination of, a rotatable windcuttingedge projecting beyond the surface of the arm.

2. In a device for material, the combination of, a rotatable winding thearms with its cutting edge projecting beyond the surface of the arm, andmeans for moving the knife in the direction of extension of the arm tosever the material wound on the reel.

3. In a device for winding and cutting web,

material, the combination of, a rotatable winding reel comprising aplurality of arms held in spaced relationship t ereon' and each armhaving a surface for engaging material, the ing reel comprising awinding and cutting web the combination of, a rotatable winding of armsheld in adjustable the reel.

9. In a device for winding and cutting web material, the combination ofa rotatable winding to sever the material wound on the reel.
